Abstract

L'invention concerne en général le domaine des piles rechargeables au lithium, et en particulier une conception d'électrodes positives de pile au lithium-ion présentant une protection de surcharge d'impulsions à vitesse élevée. Ainsi, l'invention concerne des dispositifs électrochimiques contenant une cathode comprenant au moins une matière positive primaire et au moins une matière positive secondaire; une anode et un électrolyte non aqueux comprenant un additif de navette redox; le potentiel d'oxydoréduction de cet additif de navette redox étant supérieur au potentiel d'oxydoréduction de la matière positive primaire. Le potentiel d'oxydoréduction de l'additif de navette redox est inférieur au potentiel d'oxydoréduction de la matière positive secondaire. L'additif de navette redox est stable au moins jusqu'au potentiel d'oxydoréduction de la matière positive secondaire.
